DTC Dynamic Traction
Control
The concept The DTC system is a version of the DSC in
which forward momentum is optimized.
The system ensures maximum forward mo‐
mentum on special road conditions, e.g., unp‐
lowed snowy roads, but driving stability is lim‐
ited.
It is therefore necessary to drive with appropri‐
ate caution.
You may find it useful to briefly activate DTC
under the following special circumstances:▷When driving in slush or on uncleared,
snow-covered roads.▷When rocking the vehicle or driving off in
deep snow or on loose surfaces.▷When driving with snow chains.
Deactivating/activating DTC Dynamic
Traction Control
Activating the Dynamic Traction Control DTC
provides maximum traction on loose ground.
Driving stability is limited during acceleration
and when driving in bends.
Activating DTC Press the button.
TRACTION is displayed in the instru‐
ment cluster and the indicator lamp for DSC
OFF lights up.
Deactivating DTC Press the button again.
TRACTION and the DSC OFF indica‐
tor lamp go out.
Indicator/warning lamps
When DTC is activated, TRACTION is dis‐
played in the tachometer.
The indicator lamp lights up: DTC Dy‐
namic Traction Control is activated.
xDrive xDrive is the all-wheel-drive system of your ve‐
hicle. Concerted action by the xDrive and DSC
further optimize traction and driving dynamics.
The xDrive all-wheel-drive system variably dis‐
tributes the drive forces to the front and rear
axles as demanded by the driving situation and
road surface.

HDC Hill Descent Control
The concept HDC is a downhill driving assistant that auto‐
matically controls vehicle speed on steep
downhill gradients. Without applying the
brakes, the vehicle moves at slightly more than
walking speed.
Seite 133Driving stability control systemsControls133
Online Edition for Part no. 01 40 2 926 740 - X/13
Hill Descent Control can be activated at
speeds below approx. 22 mph/35 km/h. When
driving downhill, the vehicle reduces its speed
to approx. walking speed and then keeps its
speed constant.
As long as there is active braking, the system
is on standby. The system does not brake the
vehicle during this time.
Use HDC in low gears or in transmission posi‐
tion D or R only.
Increasing or decreasing vehicle
speed
Specify desired speed in the range from ap‐
prox. 4 mph/6 km/h to approx. 15 mph/25 km/h
using the rocker switch of the cruise control on
the steering wheel. Vehicle speed can be
changed by lightly accelerating.▷Press up the rocker switch to the point of
resistance: the speed increases gradually.▷Press up the rocker switch past the point
of resistance: the speed increases while
the rocker switch is pressed.▷Press down the rocker switch to the point
of resistance: the speed decreases gradu‐
ally.▷Press down the rocker switch past the
point of resistance: when driving forward,
the speed decreases to approx.
6 mph/10 km/h; when reversing, the speed
decreases to approx. 4 mph/6 km/h.Activating HDC
Press the button; the LED above the but‐
ton lights up.
Deactivating HDC Press the button again and the LED goes
out. HDC is automatically deactivated
above approx. 37 mph/60 km/h.
Display in the instrument cluster The selected speed is displayed
in the speedometer.
▷Green: the system is actively
braking the vehicle.▷Orange: the system is on
standby.
Malfunction
A message is displayed in the instrument clus‐
ter. HDC is not available, e.g., due to elevated
brake temperatures.
Active Steering
Active Steering varies the steering angle of the
wheels in relation to the steering wheel move‐
ment as a function of the speed.
At lower speeds, for example during turning or
maneuvering, the steering angle is increased,
that is to say the steering becomes more di‐
rect.
Seite 134ControlsDriving stability control systems134
Online Edition for Part no. 01 40 2 926 740 - X/13
At higher speeds, the steering angle is increas‐
ingly reduced.
This enables even more precise handling at
high speeds and more responsive steering
with reduced steering angle at low speeds.
Active roll stabilization
The concept The system reduces the lateral inclination of
the vehicle that occurs during rapid driving in
curves or during quick evasive maneuvers.
Driving stability and driving comfort are in‐
creased under all driving conditions. The sys‐
tem utilizes active stabilizer bars on the front
and rear axles that react immediately to all driv‐
ing situations.
Programs The system offers two different programs.
The programs can be selected via the Driving
Dynamics Control, refer to page 135.
SPORT
Sporty tuning for greater driving agility.
COMFORT
Comfort-oriented tuning for optimal comfort.
Vertical Dynamic Control The concept This system reduces undesirable vehicle mo‐
tion when using a dynamic driving style or trav‐
eling on uneven road surfaces.
The system enhances driving dynamics and
comfort as required for the road surface and
driving style.
Programs The system offers several different programs.The programs can be selected via the Driving
Dynamics Control, refer to page 135.
SPORT/SPORT+
Consistently sporty control of the shock ab‐
sorbers for greater driving agility.
COMFORT/ECO PRO Balanced tuning.
Self-leveling suspension The concept The self-leveling suspension keeps the vehicle
height and ground clearance constant. The
height of the vehicle at the rear axle is main‐
tained at a predefined level under all load con‐
ditions.
The system ensures consistent comfort by
keeping spring travel constant in all driving sit‐
uations.
Malfunction
A Check Control message is displayed. A mal‐ function has occurred in the self-leveling sus‐
pension. Vehicle handling may be altered and
driving comfort may be noticeably reduced.
Visit your nearest service center.
Driving Dynamics ControlThe concept
The Driving Dynamics Control can be used to
adjust the driving dynamics of the vehicle. For
this purpose various programs are available for
selection that are activated via the two buttons
of the Driving Dynamics Control and the DSC
OFF-button.Seite 135Driving stability control systemsControls135

Switching off Deactivated or interrupted system
If the system is deactivated or inter‐
rupted, actively intervene by braking, steering
and, if necessary, with evasive maneuvers; oth‐
erwise, there is the danger of an accident oc‐
curring.◀
If switching off the system while stationary,
press on the brake pedal at the same time.
Press the button on the steering
wheel.▷If active: press twice.▷If interrupted: press once.
The displays go out. The stored desired speed
and distance are deleted.
Interrupting Press the button on the steering
wheel.
If interrupting the system while stationary,
press on the brake pedal at the same time.
The system is automatically interrupted in the
following situations:
▷When the brakes are applied.▷When transmission position D is disen‐
gaged.▷When DTC Dynamic Traction Control is
activated or DSC is deactivated.▷When DSC is actively controlling stability.▷When SPORT+ is activated with Driving
Dynamics Control.▷If the safety belt and the driver's door are
opened when the vehicle is standing still.▷If the system has not detected objects for
an extended period, e.g., on a road withvery little traffic without road edge line
markings.▷If the detection range of the radar is dis‐
rupted, for example, by dirt or heavy fog.
Maintaining/storing the speed
Press the button.
Or:
Press the rocker switch while the system is in‐
terrupted.
When the system is switched on, the current
speed is maintained and stored as the desired
speed.
This is displayed in the speedometer and
briefly in the instrument cluster. Displays in the
instrument cluster, refer to page 142.
When cruise control is maintained or stored,
DSC Dynamic Stability Control is switched on,
if necessary.
Changing, maintaining, and storing
the speed
The rocker switch can be pressed while the
system is interrupted to maintain and store the
current speed. DSC Dynamic Stability Control
is switched on, if necessary.

Speed differences
Large differences in speed relative to
other vehicles cannot be compensated by the
system for example in the following situations:▷When catching up rapidly with a truck.▷When another vehicle suddenly swerves
into the wrong lane.▷When stationary objects are approached at
speed.◀
Press the rocker switch up or down repeatedly
until the desired speed is set.
If active, the displayed speed is stored and the
vehicle reaches the stored speed if the road is
clear.
▷Each time the rocker switch is pressed to
the point of resistance, the desired speed
increases or decreases by approx.
1 mph/1 km/h.▷Each time the rocker switch is pressed
past the point of resistance, the desired
speed increases or decreases by a maxi‐
mum of 5 mph/10 km/h.
Hold the rocker switch in position to repeat the
action.
Distance Selecting a distance
Adjust the distance according to the traf‐
fic and weather conditions; otherwise, there is
the danger of an accident occurring. Maintain
the prescribed safety distance.◀
